N.p., 7 Sept. 2004. Web. 03 Dec. 2013.〕The Lybiidae family has a total of 42 species that occur throughout the continent of Africa from the tip of the Cape Peninsula to the fringes of the Sahara desert. Out of the 42 species in this family, the ''Lybius'' genus contains 11 barbet species. These 11 species are the most frequently encountered group of African barbets.〔("Africa’s Barbets." ) 10,000 Birds. N.p., n.d.
